Screen burn is where a ghost image of a channel logo is left on the television screen once the set has been turned off or onto another channel. The problem doesn’t affect LCD TVs, but plasma TVs and old fashioned CRT TVs are susceptible. However, broadcasters have toned down the brightness of their logos, and the latest plasma TVs boast screen-cleaning technologies to combat the problem. In Which? tests, images burnt on to the plasma TV screen after a day, disappeared after normal TV viewing. After leaving a channel logo on-screen for a week, only one plasma TV (out of six tested) suffered any permanent screen-burn.
